Following recent leaks and speculation, Ubisoft has officially confirmed that it will be bringing more of its titles to Steam.

The details:

Speaking with Eurogamer, the AAA publisher confirmed that Assassin’s Creed Valhalla, Anno 1800, and free-to-play Roller Champions were among the titles that will hit Steam in the near future.
"We're constantly evaluating how to bring our games to different audiences wherever they are, while providing a consistent player ecosystem through Ubisoft Connect," a Ubisoft spokesperson told Eurogamer. "Assassin's Creed Valhalla, Anno 1800, and Roller Champions are among the Ubisoft titles that will be releasing on Steam.”
Previously, games published by Ubisoft were only available for purchase on the Epic Games Store or through the company’s own storefront: Ubisoft Connect.
A couple of weeks ago, it was discovered that the Ubisoft Connect database was storing what appeared to be a Steam version of Assassin’s Creed Valhalla, prompting fans to speculate whether it would release on that platform.
When these titles release officially on Steam, it’s possible that they’ll still require players to launch them through Ubisoft Connect — similar to how things work on the Epic Games Store version of Assassin’s Creed Valhalla.

More to come?

Assassin’s Creed Valhalla has already popped up on Steam, with its store page stating its release date as December 6, 2022.
There’s no confirmation on when Anno 1800 or Roller Champions will join Valhalla; currently, neither game has a store page on Steam.
While Ubisoft is opening up more of its titles to Steam, there are still some noticeable omissions. Tom Clancy’s The Division is available through Steam, but its sequel The Division 2 remains off the platform.
It’s also unknown if the upcoming Assassins Creed Mirage, slated for release in 2023, will join Valhalla, as Steam lacks any trace of the game whereas the Epic Games Store already has a page set up and ready to go for it.
